Example one

The present embodiment provides a cleaning apparatus, as shown in fig. 1, including: a first tank 101 configured to store a first liquid, the first tank 101 being connected to a first pumping device 102; a second liquid storage tank 103 configured to store a second liquid, the second liquid storage tank 103 being connected to a second liquid pumping device 104; a first sensor 105 configured to detect a dirty state of the cleaning surface; a controller 106 in communication with the first sensor 105 and configured to: controlling the output flow of at least one of the first liquid pumping device 102 and the second liquid pumping device 104 according to the material type of the cleaning surface and the dirty state of the cleaning surface; and a cleaning member 107 configured to clean the cleaning surface with a mixed liquid of the first liquid output by the first liquid pumping device 102 and the second liquid output by the second liquid pumping device 104.

The cleaning device is a device having at least a function of mopping or cleaning a cleaning surface, and includes, but is not limited to, a cleaning machine, a sweeping robot having a mopping function, and the like. The cleaning surface can be the floor and the table top of an indoor household environment, and can also be the floor of a shopping mall, a restaurant or other indoor environments. The first liquid stored in the first tank 101 is water, for example, a user may directly add tap water into the first tank 101. The second liquid is a cleaning liquid having at least a cleaning function, and may be a cleaning liquid having a cleaning and disinfecting function, for example. The first liquid pumping device 102 and the second liquid pumping device 104 may employ a water pump, an air pump, or the like for pumping the first liquid and the second liquid from the first tank 101 and the second tank 103. The first sensor 105 may include a turbidity sensor, a Total Dissolved Solids (TDS) sensor, and the like, which can detect a degree of contamination, and is described below with reference to a cleaning apparatus as a washing machine, a cleaning surface is cleaned by a roller on a floor brush, and after cleaning, sewage is sucked into the recovery tank 109 from a floor brush suction port through the vacuum source 108, and the first sensor 105 may be disposed in the recovery channel between the floor brush suction port or the floor brush suction port and the recovery tank 109, and is used for detecting a state of the sewage sucked back from the cleaning surface, feeding parameters back to the controller 106, and the controller 106 determines a contamination state of the cleaning surface.

The controller 106 may be a general purpose processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), a single chip, an arm (acorn RISC machine) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination of these components. Also, the controller 106 may be any conventional processor, controller, microcontroller, or state machine. The controller 106 may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP, and/or any other such configuration.

In this embodiment, as shown in fig. 1, the first liquid storage tank 101 is an independent structure, and when the cleaning machine is started, the controller 106 controls the first liquid pumping device 102 to start, so as to convey the clean water in the first liquid storage tank 101 to the cleaning member 107 for cleaning. Simultaneously, the vacuum source 108 is activated to draw the wastewater into the recovery tank 109. The dirty state of the cleaning surface is determined by feeding back the dirty data to the controller 106 using the first sensor 105. If the dirty state is not a clean state, for example, the turbidity parameter or TDS parameter detected by the sensor is greater than a preset threshold, the controller 106 activates the second liquid pumping device 104 to mix the cleaning liquid with the clean water output by the first liquid pumping device 102 in the pipeline and then deliver the mixed cleaning liquid to the cleaning device for dirty cleaning. Specifically, as shown in fig. 2, the first pumping device 102 is connected to the first storage tank 101, the second pumping device 104 is connected to the second storage tank 103, and the clean water and the cleaning liquid are mixed at the tee joint element 110 and then are conveyed to the cleaning member through the conveying pipeline for cleaning.

The controller 106 controls the output flow rate of at least one of the first pumping device 102 and the second pumping device 104 according to the type of material of the cleaning surface and the contamination state. When the cleaning area is judged to be in a clean state through information data fed back by the first sensor 105, the controller 106 closes the first liquid pumping device 102 and the second liquid pumping device 104, the vacuum source 108 continues to work, sewage residue in the cleaning area is recycled, and the drying degree of the cleaning area is ensured.

The type of material of the cleaning surface may include hard types such as wood floor, floor tile, etc., soft types such as carpet, etc. The hard type is easier to clean than the soft type when the same dirt degree is achieved, the proportion of the cleaning solution can be set to be less in the hard type and more in the soft type.

In one embodiment, the logic for adding cleaning liquid specifically is as follows: when the material type is hard and the dirty state is slight dirty, the adding proportion of the cleaning solution is set to be half of the standard proportion; when the material type is hard and the dirty state is general dirty, the adding proportion of the cleaning solution is set as a standard proportion; when the material type is hard and the dirty state is heavy dirty, the adding proportion of the cleaning solution is set to be twice of the standard proportion; when the material type is soft and the dirty state is slight dirty, the adding proportion of the cleaning solution is set as a standard proportion; when the material type is soft and the dirty state is general dirty, the adding proportion of the cleaning solution is set to be twice of the standard proportion; when the material type is soft and the dirty condition is heavy dirty, the adding ratio of the cleaning liquid is set to be multiple times (for example, three times or five times) of the standard ratio, and the above-mentioned ratio logic is only an example and is not a limitation to the present application.

The controller 106 may control the output flow rate of at least one of the first pumping device 102 and the second pumping device 104 according to the logic described above. For example, when the material type is hard and the dirty state is heavy dirty, the cleaning liquid adding ratio is set to be twice as large as the standard ratio, the controller 106 may decrease the output flow rate of the first pumping device 102 by one time, keep the output flow rate of the second pumping device 104 unchanged, keep the output flow rate of the first pumping device 102 unchanged, increase the output flow rate of the second pumping device 104 by one time, or increase the output flow rate of the first pumping device 102 by one time, increase the output flow rate of the second pumping device 104 by two times, and so on.

Alternatively, the type of material of the cleaning surface may be determined by:

when the cleaning device operates, the working current of the power source for driving the cleaning piece 107 to work is monitored, and the material type of the cleaning surface is determined according to the working current, generally, the friction force between the hard or flat cleaning area and the rolling brush is small, and the working current ratio of the power source for driving the rolling brush to work is small. For soft types such as carpets, the current is relatively large;

or, the cleaning device is provided with a mode selection device (such as a switch, a knob, etc.), a user manually selects different cleaning modes according to different material types (such as a floor, a carpet, etc.), and the controller 106 can determine the material type of the cleaning surface according to the input of the user;

alternatively, as shown in fig. 3, a light sensing element 111 is disposed on the body of the floor brush or the cleaning device, and the material type is intelligently recognized by means of an algorithm.

According to the cleaning equipment of this embodiment in the cleaning process through the dirty state according to the material type of cleaning surface and cleaning surface, the output flow of at least one in first pump liquid device and the second pump liquid device of control, the mixed liquid's of two kinds of liquid of control first pump liquid device and second pump liquid device output mix the proportion to can be more intelligent and adjust the cleaning solution ratio in real time automatically, saved manual operation, greatly promoted user's use experience.

In one embodiment, as shown in fig. 4 and 5, the cleaning apparatus further comprises: a second sensor 112 disposed in the mixed liquor delivery conduit of the first and second liquids, configured to detect the mixing of the mixed liquor and feed back to the controller 106; the controller 106 is further configured to: the output flow of at least one of the first pumping fluid device 102 and the second pumping fluid device 104 is adjusted according to the mixing condition.

The second sensor 112 may be a turbidity sensor or a TDS sensor for monitoring the quality of the mixed liquid in real time and feeding back to the controller 106, and the controller 106 adjusts according to the fed back parameters, thereby ensuring that the mixing ratio is more accurate.

Example two

In this embodiment, the first liquid storage tank 101 is a collection tank 109 configured to contain the sewage collected by the cleaning surface, a filtering device 113 is disposed in the collection tank 109, and the sewage in the collection tank 109 is filtered by the first liquid pumping device 102 and then output through the filtering device 113. The other structures and control logic may adopt the structures and control logic in the first embodiment, and are not described again, and differences from the first embodiment are mainly introduced here.

As shown in fig. 6, the cleaning machine uses only one recovery tank 109, and the first reservoir is not separately provided. Before the cleaning machine works, a proper amount of solution (either clear water or sewage) is added into the recovery tank 109. When the cleaning device is started, the controller 106 controls the first liquid pumping device 102 to be started, the solution in the recovery tank 109 is filtered by the filtering device 113 and sucked out, and the sucked out purified water is conveyed to the cleaning member 107 through the pipeline. Simultaneously, the vacuum source 108 is activated to draw the wastewater into the recovery tank 109. The dirty state of the cleaning region is determined by feeding back the dirty data to the controller 106 using the first sensor 105. If the dirty state is not a clean state, for example, the turbidity parameter or TDS parameter detected by the sensor is greater than a preset threshold, the controller 106 activates the second fluid pumping device 104 to mix the cleaning fluid with the purified water output by the first fluid pumping device 102 in the pipeline and then deliver the mixed fluid to the cleaning member 107 for performing dirty cleaning. The controller 106 controls the output flow rate of at least one of the first pumping device 102 and the second pumping device 104 according to the type of material of the cleaning surface and the contamination state. When the dirty data fed back by the first sensor 105 determines that the cleaning area is cleaned, the controller 106 turns off the first liquid pumping device 102 and the second liquid pumping device 104, the vacuum source 108 continues to work, and the residual dirty water in the cleaning area is recovered, so that the dryness of the cleaning area is ensured. According to the cleaning equipment of this embodiment adopt from the collection box through the filterable purified water of filter device as liquid and cleaning solution after mixing clean, saved first liquid reserve tank to can simplify the structure, save space.

EXAMPLE III

In this embodiment, there is provided a cleaning apparatus including: a first tank 101 configured to store a first liquid; a second tank 103 configured to store a second liquid; a first sensor 105 configured to detect a dirty state of the cleaning surface; a controller 106, the controller 106 in communication with the first sensor 105 and configured to: the mixing ratio of the first liquid output from the first liquid storage tank 101 and the second liquid output from the second liquid storage tank 103 is controlled according to the type of the material of the cleaning surface and the dirty state of the cleaning surface. The cleaning device of this embodiment may adopt the overall structure shown in fig. 1 and fig. 6, and the specific structure and the control logic may refer to the first embodiment, which is not described herein again.

Optionally, the first reservoir 101 is connected to the first pumping device 102, and the controller 106 is configured to: the mixing ratio is controlled by controlling the output flow rate of the first pumping device 102.

Optionally, the first reservoir 101 is connected to the first pumping device 102, the second reservoir 103 is connected to the second pumping device 104, and the controller 106 is configured to: the mixing ratio is controlled by controlling the output flow rate of at least one of the first pumping device 102 and the second pumping device 104.

In one embodiment, the first reservoir 101 is connected to the first pumping device 102, and the first liquid from the first reservoir 101 passes through a venturi-effect mixing element 114, so that the second liquid from the second reservoir 103 is sucked into the mixing element 114 by venturi effect, wherein the cross-sectional area of the constriction region of the mixing element 114 is adjustable or the cross-sectional area of the first liquid flow conduit upstream of the constriction region is adjustable.

First, describing the venturi effect principle, as shown in fig. 7, when a liquid (or gas) flows through a pipe, the flow velocity of the liquid (or gas) increases due to the decrease of the cross-sectional area of the constriction region, and the higher the flow velocity, the lower the pressure. In fig. 7, the cross-sectional area a1 at

points

1 and 2 in the conduit is greater than a 2. The liquid (or gas) flow rate at point 2 is greater than the flow rate at point 1, i.e. V2> V1, while the pressure at point 2 is less than the pressure at point 1, i.e. P2< P1, resulting in a pressure difference between point 2 and point 1, which can be calculated as a height difference, i.e. a liquid level height difference h in the graph, according to bernoulli's equation. This pressure differential provides an external suction to the tubing at point 2.

Specifically, in the case where the mixing ratio of the cleaning liquids does not need to be adjusted, as shown in fig. 8, the clean water flows through the first pumping device 102 in the pipe, the flow rate becomes faster and the pressure becomes smaller when passing through a narrow cross section, and at this time, the cleaning liquids are sucked into the pipe due to the pressure difference, mixed with the clean water, and then conveyed to the cleaning member for cleaning. In this embodiment, it is necessary to adjust the mixing ratio of the second liquid by using the mixing element 114. The mixing ratio of the second liquid is adjusted by adjusting the cross-sectional area of the constriction region as an example. The contraction zone can be made of flexible material, the contraction zone is provided with an adjusting device, when the mixing proportion of the second liquid needs to be adjusted, the controller 106 controls the adjusting device to adjust the cross-sectional area of the contraction zone, when the cross-sectional area is reduced, the speed of the first liquid, namely clean water, passing through the contraction zone is increased, the pressure difference formed in the contraction zone is increased, and the mixing proportion of the sucked second liquid, namely cleaning liquid is increased; when the cross-sectional area of the constriction zone increases, the speed of the first liquid, i.e. clean water, through the constriction zone decreases, the pressure difference formed in the constriction zone decreases, and the mixing ratio of the sucked-off second liquid, i.e. cleaning liquid, decreases.

In this embodiment, the use of the venturi effect mixing element 114 allows for the adjustment of the mixing ratio of cleaning liquid to fresh water with the use and control of only the cross-sectional area of the constriction, simplifying the structure and control logic of the controller.

The realization by adjusting the cross-sectional area of the first liquid flow conduit upstream of the constriction region can be referred to the realization by adjusting the cross-sectional area of the constriction region described above and will not be described in detail here.

The above description describes the implementation of the mixing element 114 being made of a flexible material and having an adjustable cross-sectional area, but it is understood that the mixing element 114 may also be made of a rigid material, and that the mixing element 114 having different ratios of the cross-sectional areas of the first liquid flow conduit upstream of the constriction zone and the constriction zone is provided in advance according to the mixing ratio of the second liquid, and that the controller 106 controls the mixing element 114 to be changed to a corresponding size according to different mixing ratios, i.e. different concentrations of the cleaning liquid, when the mixing ratio needs to be adjusted. The first liquid flow path may be part of the mixing element 114, or the mixing element 114 may have only a constriction with a constricted cross-sectional area, the first liquid flow path being arranged upstream of the mixing element 114, in which implementation the mixing ratio can be controlled by controlling the cross-sectional area of the constriction.

In the present embodiment, a second sensor 112 may also be disposed in the mixed liquid delivery pipeline, disposed in the mixed liquid delivery pipeline of the first liquid and the second liquid, configured to detect the mixing condition of the mixed liquid and feed back to the controller 106; the controller 106 may be configured to: the cross-sectional area of the constriction of the mixing element 114 is adjusted to the mixing situation, thereby ensuring a more precise mixing ratio.

Application scenario one

A user cleans the cleaning surface by using the cleaning machine, and the cleaning machine is started after the cleaning machine is placed on the cleaning surface. A controller in the cleaning machine controls a first pump liquid device of the clean water tank to be started, and clean water in the clean water tank is conveyed to the ground brush device to be cleaned. Simultaneously, a vacuum source is started, and sewage is sucked into the recovery box by using a suction port of the floor brush. And feeding back the dirt data to the controller by using the sensor to judge the dirt state of the cleaning surface. If the dirty state is not a clean state, for example, the turbidity parameter or the TDS parameter detected by the sensor is greater than a preset threshold value, the controller controls the second pump liquid device connected with the cleaning liquid barrel to be started, the cleaning liquid and the clean water output by the first pump liquid device are mixed in the pipeline and then are conveyed to the floor brush device, and dirty cleaning is performed.

When the cleaning surface is determined to be the floor in the type of material, and the dirty state of the cleaning surface detected by the first sensor is heavily dirty, the output flow of the second liquid pumping device is controlled to be doubled compared with the standard quantity, the output flow of the first liquid pumping device is controlled to be unchanged, and the adding proportion of the cleaning liquid is doubled compared with the standard proportion. When the preset cleaning area is reached and the dirty state of the cleaning surface detected by the first sensor is slightly dirty, the output flow of the second liquid pumping device is controlled to be reduced by one time compared with the standard amount, and the output flow of the first liquid pumping device is unchanged, so that the adding proportion of the cleaning liquid is half of the standard proportion.

Application scenario two

A user cleans the cleaning surface by using the cleaning machine, and the cleaning machine is placed on the cleaning surface. The cleaning machine only uses one recovery tank, and a clear water tank is not independently arranged.

Simultaneously, a vacuum source is started, and sewage is sucked into the recovery box by using a suction port of the floor brush. And feeding back the dirt data to the controller by using the sensor to judge the dirt state of the cleaning area. If the dirty state is not a clean state, for example, the turbidity parameter or the TDS parameter detected by the sensor is greater than a preset threshold value, the controller controls the second pump liquid device connected with the cleaning liquid barrel to be started, the cleaning liquid and the purified water output by the first pump liquid device are mixed in the pipeline and then are conveyed to the floor brush device, and dirty cleaning is carried out.
